Description of problem:
When running spacewalk-hostname-rename on a satellite withOUT embedded database, spacewalk-hostname rename says:

CONFIG PARSE WARNING: File not found or can't be read /usr/share/rhn/config-defaults/rhn_pgversion.conf
CONFIG PARSE WARNING: key not found in config default dict ('pgversion',)

I do not know of any issues caused by this yet. However, these error messages are not something users should see, particularly the "key not found" one.

How reproducible:
Deterministic

Steps to Reproduce:
On Satellite running against ManagedDB:
#spacewalk-hostname-rename <IP>
CONFIG PARSE WARNING: File not found or can't be read /usr/share/rhn/config-defaults/rhn_pgversion.conf
CONFIG PARSE WARNING: key not found in config default dict ('pgversion',)
